View Full Version : Found "cheap" flip up seat bolster option

11-03-2012, 10:32 AM
My 2007 X1 didn't have the flip up drivers seat bolster.
Tried a couple of mastercraft dealerships, but they couldn't come up with a part number or the brackets.
Took a chance on a pair of seat brackets from Great Lake Skipper.
Only $29.99. They have "strange" price management at GLS. They have 3 different sets of brackets, that all look the same, from $30-$50.
I went with these:
Larson 22113178 Tecla MF2215 Seat Roll Back Fold Up Boat Bracket Hinges (Set of 2)
Sold in sets of 2.


Manufacturer: Tecla
Model: MF2215
Vendor: Larson Boats
Part number: 22113178
Material: Aluminum (stainless steel rivets)
Color: White
Overall Measurements: 8 3/8" W x 2 1/8" H x 2 1/4" D (overall -- fully compressed)
Mounts: Base -- 7 3/8" W x 4 3/4" H x 2 1/4" D (overall -- fully extended)
Mounts: (8) 5 1/6" dia. mounting holes with 3/4" and 1 1/2" (countersunk) center on center; and 3/4" and 2 1/2" center on center


They worked perfectly! Much better than the old cushion I used all summer.

New bracket on top, old on bottom

test fitting with the part number exposed

Installed and flipped up
Sure is dirty! Previously, the bolster was fixed, never saw how dirty it was between the cushions

and in the down position.
Looks like its "off" but that's just the angle I was taking the picture. Everything lines up perfect.
$40 with shipping and WI tax, good money spent-

I dont have that bracket under my seat. How did you cut your bottom cusion into two parts? Really would like to convert my seat to a double like yours.

That was the easy part, the seat already had two separate cushions from the factory. But mastercraft used the fixed straight brackets that cost $0.50 to make instead of the $5.50 brackets!

Hello all:

I have been trying to follow along. I couldn't find the Tecla bracket on Ebay so I contacted the manufacturer. They were easy to work with. $77 had the Tecla Bracket delivered to my door.



All is looking good. I head out to the garage to get started.


I easily remove the seat bottom:


and I CANNOT get the screws to budge from my seat. I even tried an impact phillips screwdriver. Am I missing something obvious? I couldn't see any bolt on the back side or any way to access a bolt.

Here are the screws in question:


Any help is appreciated.

Thanks much, Steve.

Problem solved.

To answer my own questions, there is NOT a backing bolt. On both the seat bottom and the bolster there are threaded metal inserts. On the seat bottom there was a thread-lock used.

The screws were an absolute beast to remove. I finally made some progress by using a heat gun to heat everything up and I purchased a Philips screwdriver with a hex portion so I could use a wrench for additional leverage. Here is the seat with everything removed.


Here is the old straight bracket. You can see the dried residue of whatever threadlock MC used. The stuff was tough.


I purchased new screws as the old ones were trashed from my efforts to remove them. The brackets went on fairly easily but I did have the "leverage" the bolster a bit to get things aligned. I attached the brackets to the bolster first. Here the set is in the down postion:


And here it is up:


My wife just laughs at me....

I'm very happy with the result. Thanks much for the idea Hartland!

Cheers, Steve.
